DETECTOR-BAR CLIP AND STOP.

SPECIFICATION forming part Of Letters Patent NO. 698,451, dated April29, 1902.

Application filed October 10, 1901. $erial No. 78,174. (No model.)

F0 all whom it may concern.-

Be it known that 1, JAMES CHALMERS, J r., of Swissvale, in the county ofAllegheny and State of Pennsylvania, have invented a certain new anduseful Improvement in Detector-Bar Clips and Stops, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification, inwhich- Figure 1 is an end view of the clip, showing the railroad-rail incross-section and a carwheel by dotted lines. Fig. 2 is a plan view ofthe railroad-rail, the clip, and a portion of the detector-bar. Fig. 3is a side elevation of the same, showing the detector-bar stop; and Fig.4 is a detached view of the adjustable stop.

Like symbols of reference indicate like parts wherever they occur.

The object of my invention is to provide simple and efiicient means forsecuring the detector-bar in position alongside of the rail:

and to provide an adjustable and rigid stop whereby the movement of thedetector-bar may be varied.

I will now describe my invention so that others skilled in the art maymanufacture and use the same.

In the drawings, 2 represents the usual derector-bar, which may be usedfor any of the ordinary purposes, such as looking switch mechanism whena car or train of cars passes over the same. This detector-bar ispivoted to a pivotal link or radial arm 3 in the usual manner,- and thisarm is in turn pivoted to a bracket lyextending from the body of theclip 5. The body of this clip 5 is formed of two plates or leaves a. andb at an angle to each other and provided with screw or bolt holes, bymeans of which screws or bolts 6 and 7 are employed to secure the clipto the side and top of the railroad-tie 8 alongside of the railroad-rail9. Extendingvertically from the horizontal leaf Z) of the clip 5 is apost 10, through which extends a bolt 11, provided with a nut 12. Thisboltpasses through a slot 13 in the movable or adjustable detector-barrest 14, which, owing to the slot, may be adjusted vertically byloosening and tightening the nut 12. This rest 14 is provided with aledge or shelf 15, which is parallel with the top of the post 10 andserves as a rest for the bottom edge of the detectorbar 2. By adjustingthe stop 14 up or down the height of the rest may be varied. The innerface of the stop 14, where it comes in contact with the post/'10, andthe outer face.

two lag-screws being required, one being.

placed through the top leaf of the clip and extending down into the topof the railroadtie and the other through the side leaf of the clip andextending into the side of the tie, thus dispensing with hook, bolts,nuts, and nut locks and avoiding the danger of the fasten= ings becomingloose and shifting out of place. It also enables the use of along linkor radial arm for supporting the detector-bar, owin g to the loweredposition of the clip-bracket, which results in case of operation andgives a proper rise to the detector-bar. It also onables either anadjustable stop to be employed by moving and securing in an elevatedposition the stop let or the use of a solid stop by lowering the stop 14below the level of the post 10, in which case the top of the post actsas a fixed stop for the detector-bar. These and other advantages of myinvention will be apparent to those skilled in the art;

Although I have described and shown a certain number of securing-screws,I do not desire to limit myself to the same, nor do I desire to limitmyself to the exact shape and configuration of the parts as shown in thedrawings. I

Having thus described my invention, what I claim, and desire to secure'by Letters Patent, isp l 1. A clip for supporting detector-bars, having a body formed of two leaves at an angle to each other, having asuppofting-bracket extending from the lower leaf, to which bracket thesupporting-arm of the detectorbar is to be pivoted, and having aperturesor recesses for bolts or screws by which the clip is to be secured tothe railroad-tie.

2; A clip for supporting detector-bars, consisting of leaves formed atan angle to each other for attachment to the tie, and having a bracketfor the radial supporting-arm, extending from one leaf, and adetector-bar stop extending from the other leaf.

3. A clip for supporting detector-bars, consisting of leaves formed atan angle to each other for attachment to the'tie, a bracket extendingfrom one leaf, a fixed detector-bar stop extending from the other leaf,and a second stop adj ustably secured to the fixed stop.

4. A clip for supporting detector-bars, consisting of two leaves formedat an angle to each other for attachment to the tie, a bracket extendingfrom one leaf and afixed stop from the other, and a second stopadjustably secured to the fixed stop, and serrations or teeth formed onthe meeting faces of the fixed and adjustable stops.

In testimony whereof I have hereunto set my hand.
